Then a fast probabilistic method to 20% 的速度增长。根据国家“十一五”规划，2020 evaluate total transfer capability (TTC) in power system 年我国风电装机容量将达到 30 GW，占全国电力总 including large-scale wind farms is developed, in which wind 装机容量的 3% 。随着越来越多大型风电场直接连 speed, loads, generation and device outage uncertainties are 入输电系统，有关风电并网的相关研究工作日益得 considered at the same time. Compared with traditional methods, 到重视[1-6] 。 the proposed method can not only consider conveniently the influence of wind power randomness, but also significantly 可用输电能力(available trans
